in reply to Pattern Finding

This works... but probably only on account of villany. I think for something to be considered a "pattern", it has to show up TWICE, not just once.
$_ = "helloworldhellohellohihellohiworld"; m{ (?{ local ($c1, $c2, $c3) = (0,0,0) }) ^ (.+?) (?: \1 (?{ local $c1 = $c1 + 1 }) )* (.+?) (?: (?: \1 (?{ local $c1 = $c1 + 1 }) ) | (?: \2 (?{ local $c2 = $c2 + 1 }) ) )* (.+?) (?: (?: \1 (?{ local $c1 = $c1 + 1 }) ) | (?: \2 (?{ local $c2 = $c2 + 1 }) ) | (?: \3 (?{ local $c3 = $c3 + 1 }) ) )* (?(?{ $c1 && $c2 && $c3 })|(?!)) $ }x and print "<$1> <$2> <$3>\n";
